## Description

## Functions

### e_dbus_source_get_uid ()

    const gchar *
    e_dbus_source_get_uid (EDBusSource *object);

Gets the value of the "UID" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `e_dbus_source_dup_uid()` if on another thread.

[skip]

#### Parameters

object | A EDBusSource. |

#### Returns

The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object` .

[transfer none]

### e_dbus_source_dup_uid ()

    gchar *
    e_dbus_source_dup_uid (EDBusSource *object);

Gets a copy of the "UID" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

[skip]

#### Parameters

object | A EDBusSource. |

#### Returns

The property value or `NULL` if the property is not set. The returned value should be freed with `g_free()`.

[transfer full]

### e_dbus_source_set_uid ()

    void
    e_dbus_source_set_uid (EDBusSource *object,
                           const gchar *value);

Sets the "UID" D-Bus property to `value` .

Since this D-Bus property is not writable, it is only meaningful to use this function on the service-side.

[skip]

#### Parameters

object | A EDBusSource. |
value | The value to set. |

### e_dbus_source_get_data ()

    const gchar *
    e_dbus_source_get_data (EDBusSource *object);

Gets the value of the "Data" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `e_dbus_source_dup_data()` if on another thread.

[skip]

#### Parameters

object | A EDBusSource. |

#### Returns

The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object` .

[transfer none]

### e_dbus_source_dup_data ()

    gchar *
    e_dbus_source_dup_data (EDBusSource *object);

Gets a copy of the "Data" D-Bus property.

[skip]

#### Parameters

## Types and Values

### EDBusSource

    typedef struct _EDBusSource EDBusSource;

Abstract interface type for the D-Bus interface org.gnome.evolution.dataserver.Source.

### struct EDBusSourceSkeleton

    struct EDBusSourceSkeleton;

## Property Details

### The `“connection-status”` property

      “connection-status”        gchar *

Represents the D-Bus property "ConnectionStatus".

Since the D-Bus property for this GObject property is both readable and writable, it is meaningful to both read from it and write to it on both the service- and client-side.

Flags: Read / Write

Default value: NULL

### The `“data”` property

      “data”                     gchar *

Represents the D-Bus property "Data".

Since the D-Bus property for this GObject property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.

Flags: Read / Write

Default value: NULL

### The `“uid”` property

      “uid”                      gchar *

Represents the D-Bus property "UID".

Since the D-Bus property for this GObject property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.

Flags: Read / Write

Default value: NULL

## Signal Details

### The `“authenticate”` signal

    void
    user_function (EDBusSource *object,
                   GStrv        arg_credentials,
                   gpointer     user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "Authenticate" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A EDBusSource. |
arg_credentials | Argument. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since: 3.16

### The `“credentials-required”` signal

    void
    user_function (EDBusSource *object,
                   gchar       *arg_reason,
                   gchar       *arg_certificate_pem,
                   gchar       *arg_certificate_errors,
                   gchar       *arg_dbus_error_name,
                   gchar       *arg_dbus_error_message,
                   gpointer     user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "CredentialsRequired" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A EDBusSource. |
arg_reason | Argument. |
arg_certificate_pem | Argument. |
arg_certificate_errors | Argument. |
arg_dbus_error_name | Argument. |
arg_dbus_error_message | Argument. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“handle-get-last-credentials-required-arguments”` signal

    gboolean
    user_function (EDBusSource           *object,

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `GetLastCredentialsRequiredArguments()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_source_complete_get_last_credentials_required_arguments()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusSource. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

Since: 3.16

### The `“handle-invoke-authenticate”` signal

    gboolean
    user_function (EDBusSource           *object,
                   GDBusMethodInvocation *invocation,
                   GStrv                  arg_credentials,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `InvokeAuthenticate()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_source_complete_invoke_authenticate()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusSource. |
invocation | A GDBusMethodInvocation. |
arg_credentials | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `InvokeCredentialsRequired()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_source_complete_invoke_credentials_required()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `UnsetLastCredentialsRequiredArguments()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_source_complete_unset_last_credentials_required_arguments()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusSource. |
